Safety Precautions Please read the following safety precautions carefully.

WARNING: Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death. Remove all power from the PowerFlex drive, and then verify power has been discharged before installing or removing the option module.WARNING: Risk of injury or equipment damage exists. Only personnel familiar with drive and power products and the associated machinery should plan or implement the installation, startup, configuration, and subsequent maintenance of the drive using the option module. Failure to comply may result in injury and/or equipment damage.WARNING: Risk of equipment damage exists. The option module contains electrostatic discharge (ESD) sensitive parts that can be damaged if you do not follow ESD control procedures. Static control precautions are required when handling the option module. If you are unfamiliar with static control procedures, see Guarding Against Electrostatic Damage, publication 8000-4.5.2.WARNING: Risk of injury or equipment damage exists. If the option module is transmitting control I/O to the drive, the drive may fault when you reset the option module. Determine how your drive will respond before resetting the module.WARNING: Risk of injury or equipment damage exists. Host Parameters 33 [Comm Flt Action] and 34 [Idle Flt Action] let you determine the action of the option module and connected drive if I/O communication is disrupted, the controller is idle, or Acyclic messaging for drive control is disrupted. By default, these parameters fault the drive. You can set these parameters so that the drive continues to run, however, precautions should be taken to verify that the settings of these parameters do not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable or a controller in idle state).WARNING: Risk of injury or equipment damage exists. When a system is configured for the first time, there may be unintended or incorrect machine motion. Disconnect the motor from the machine or process during initial system testing.WARNING: Risk of injury or equipment damage exists. The examples in this publication are intended solely for purposes of example. There are many variables and requirements with any application. Rockwell Automation does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.

Installing the Option Module

This chapter provides instructions for installing the option module in a PowerFlex 750-Series product.

Preparing for an Installation Before installing the option module, do the following:

• Read the PROFIBUS Installation Guideline for details on PROFIBUS networks.

• Verify that you have all required equipment.

Setting the Endianness and Node Address Switches

Set the Endianness of the option module with Byte Swap switch 8 (see Figure 1). The Byte Swap switch can be set to either open ‘0’ (little-endian) or closed ‘1’ (big-endian) data formats for the cyclic data exchanged on the network. The cyclic data consists of the following items:

• CTRL: Logic Command Word (4 bytes)• REF: Speed Reference (4 bytes)• STAT: Logic Status Word (4 bytes)• FEEDBACK: Speed Feedback (4 bytes)• 0…16 Datalinks (4 bytes each)

Depending on the setting of the Byte Swap switch 8, the 4 bytes for each of the preceding data items are swapped.

Figure 1 - Setting Option Module Node Address Switches

Set the Node Address by setting Node Address switches 1...7 to their binary equivalent, where '0' and '1' indicate switch positions 'Open' and 'Closed' respectively. Table 1 lists node addresses and the corresponding Node Address switch settings required to set that respective address.

IMPORTANT Each node on the PROFIBUS network must have a unique address. Set the node address before power is applied because the option module detects the node address during initialization (Power On Reset). To change a node address, you must set the new value and then remove and reapply power to (or reset) the option module.

Chapter 2 Installing the Option Module

Descriptions of node address values are as follows.

The switch settings can be verified by viewing Device Parameter 06 [Net Addr Act], a read-only parameter, with any of the following drive configuration tools:

• PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM• Connected Components Workbench software

Connecting the Option Module to the PowerFlex 750-Series Product

1. Insert the option module into Port 4, 5, or 6 and tighten the module mounting screws into the pod mounting bracket. To properly ground the module to the PowerFlex 750-Series product, torque both mounting screws to 0.45…0.67 N•m (4.0…6.0 lb•in).

2. When another module (I/O, encoder, communication, and so forth) resides in the adjacent port to the left of the 20-750-PBUS option module—and the lower mounting screw of that module is a larger T15 Torx head screw, perform addition steps 2a through 2d. If the port is empty or the adjacent module already uses the smaller T8 Torx head mounting screws, save this spare screw for future use.

The option module is shipped with a small bag containing a spare T8 Torx head mounting screw and an adhesive-backed polycarbonate insulator strip. The larger T15 Torx head mounting screw on the adjacent left module may electrically contact the metal PROFIBUS cable connector when attached to the PROFIBUS module. The polycarbonate insulator strip is provided to help prevent electrical contact between the smaller T8 Torx head mounting screw and the PROFIBUS cable metal connector when attached to the PROFIBUS module. Either of these possible electrical contact situations may cause faulty operation. To help prevent this, perform the following steps.

a. Remove the adjacent module’s lower mounting screw, the T15 Torx head screw closest to the bottom of the pod mounting bracket.

b. Replace the larger T15 Torx head screw with the smaller, spare T8 Torx head mounting screw.

c. Tighten the mounting screw to the pod mounting bracket to properly ground the adjacent module to the drive. Torque the screw to 0.45…0.67 N•m (4.0…6.0 lb•in).

d. Attach the adhesive-backed polycarbonate strip to the metal PROFIBUS cable connector in a location that prevents electrical contact between the connector and the adjacent module’s lower mounting screw when the connector is attached to the PROFIBUS module.

Node Address Value Description

00If the Node Address value is set to ‘00’, the option module uses Device Parameter 05 [Net Addr Cfg] to set the Node Address. See Setting the Node Address on page 30.

01…125 Node address used by the option module.

126 The default address setting.

IMPORTANT Remove power from the product before installing the option module in the control pod.

To remove the captive T15 Torx head screw, the module must be removed to back the screw out of the mounting clip.

Chapter 2 Installing the Option Module

Configuring and Verifying Key Parameters

PowerFlex 750-Series products can be separately configured for the control and Reference functions in various combinations. For example, you could set the product to receive control commands from a peripheral or terminal block, with the Reference coming from the network. You could also set the product to receive its control from the network with the Reference coming from another peripheral or terminal block. Or you could set the product to receive both its control and Reference from the network.

The steps in this section assume that the product will receive the Logic Command and Reference from the network. In this process, you will associate the port where the PROFIBUS option module is installed with the applicable speed reference or velocity reference parameter. In this example, the screen captures reflect Connected Components Workbench and Port 4 is used. The process for other configuration tools will vary. This process is not applicable to bus supplies.

1. 753/755 - Verify that Parameter 0:301 [Access Level] is set to ‘1’ (Advanced) or ‘2’ (Expert) to access the required parameters in this procedure.

755T - Verify that Parameter 0:30 [Access Level] is set to ‘1’ (Advanced) or ‘2’ (Expert) to access the required parameters in this procedure.

2. 753/755 - Select the Value column for Parameter 0:545 [Speed Ref A Sel], type 874 in the Search field, then double-click the Port 4 Reference parameter to select it. See the PowerFlex 750-Series Programming Manual, publication 750-PM001, for the numeric value to use for other ports.

755T - Select the Value column for Parameter 10:1800 [VRef A Sel], type 217 in the Search field, then double-click the Port 4 Reference parameter to select it. See PowerFlex Drives with TotalFORCE® Control Programming Manual, publication 750-PM100, for the numeric value to use for other ports.

3. 753/755: Verify that Parameter 0:930 [Speed Ref Source] is reporting that the source of the Reference to the drive (Port 0) is the port in which the option module is installed (for example, Port 4 Reference).

This ensures that any Reference commanded from the network can be monitored by using drive Parameter 0:002 [Commanded SpdRef]. If a problem occurs, this verification step provides the diagnostic capability to determine whether the drive/option module or the network is the cause.

755T: Verify that Parameter 10/11:350 [VRef Source] is reporting that the source of the Reference to the drive (Port 0) is the port in which the option module is installed (for example, Port 4 Reference).

This ensures that any Reference commanded from the network can be monitored by using Parameter 10/11:1914 [VRef Commanded]. If a problem occurs, this verification step provides the diagnostic capability to determine whether the drive/option module or the network is the cause.

4. If hard-wired discrete digital inputs are not used to control the drive, verify that all unused digital input drive parameters are set to ‘0’ (Not Used).

Configuring the Option Module

This chapter provides instructions and information for setting the parameters to configure the option module.

For a list of parameters, see Appendix B, Option Module Parameters. For definitions of terms in this chapter, see the Glossary.

Configuration Tools The option module stores parameters and other information in its own nonvolatile storage (NVS) memory. You must, therefore, access the option module to view and edit its parameters. The following tools can be used to access the option module parameters.

Chapter 3 Configuring the Option Module

Using the PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM to Access Parameters

If your drive has an enhanced PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, it can be used to access parameters in the option module.

1. Display the Status screen, which is shown on HIM power-up.

2. Use the or key to scroll to the Port in which the option module is installed.

3. Press the PAR# soft key to display the Jump to Param # entry popup box. 4. Use the numeric keys to enter the desired parameter number, or use the

▲ or ▼ soft key to scroll to the desired parameter number.

For details on viewing and editing parameters, see the PowerFlex 20-HIM-A6/-C6S HIM (Human Interface Module) User Manual, publication20HIM-UM001.

Setting the Node Address If the option module Node Address switches (Figure 1) are set to ‘00’ (Program), the value of Device Parameter 05 [Net Addr Cfg] determines the node address. When the Node Address switches are in any other combination of positions, the switches determine the node address.

1. Set the value of Device Parameter 05 [Net Addr Cfg] to a unique node address.

2. Reset the option module; see Resetting the Option Module on page 32.

Setting a Leader-Follower Hierarchy (Optional)

This procedure is only required if Datalinks are used to write or read data of the drive or its connected peripherals. A hierarchy determines the type of device with which the option module exchanges data. In a Leader-Follower hierarchy, the option module exchanges data with a PROFIBUS leader, such as a ProSoft MVI56-PDPMV1 PROFIBUS DP scanner. This scanner integrates, as a third-party module, in a ControlLogix controller backplane to allow PROFIBUS DP communications.

Enable Datalinks To Write Data

The controller output image (controller outputs-to-drive) can have 0...16 additional 32-bit parameters (Datalinks). They are configured using Host Parameters 01 [DL From Net 01] through 16 [DL From Net 16]. The data type of a Datalink can be either a 32-bit REAL (floating point) or 32-bit integer. The number of Datalinks actively used is controlled by the connection size configured in the controller.

Chapter 3 Configuring the Option Module

When using a ControlLogix controller and the Generic Profile, configure the Datalink parameters now as described in this section.

Host Parameters 01 [DL From Net 01] through 16 [DL From Net 16] control which parameters in the drive, option module, or any other connected peripheral receive the values from the network. You can use the PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, or another drive configuration tool such as Connected Components Workbench, to select the drive or peripheral by port number and the parameter by name. As an alternate method, the parameter value can be set manually by number using this formula:

From Net Parameter Value = (10000 * port number) + (Destination Parameter Number)

For example, suppose you want to use Host Parameter 01 [DL From Net 01] to write to Parameter 03 of an optional encoder module plugged into drive Port 5. Using the formula, the value for Host Parameter 01 [DL From Net 01] would be (10000 * 5) + (3) = 50003.

Follow these steps to enable Datalinks to write data.

1. Set the values of only the required number of contiguous controller-to-drive Datalinks needed to write data to the drive and that are to be included in the network I/O connection.

2. Reset the option module; see Resetting the Option Module on page 32. 3. Since the Logic Command and Reference is always used in the option

module, configure the parameters in the PowerFlex 750-Series product to accept the Logic Command and Reference from the option module.

4. 753/755: When using the controller for speed reference via the option module, set Parameter 0:545 [Speed Ref A Sel] to reflect the port where the option module is installed (typically Port 4, which has a value of 874).

755T: When using the controller for velocity reference via the option module, set Parameter 10:1800 [VRef A Sel] to reflect the port where the option module is installed (typically Port 4, which has a value of 217).

5. 753/755: Verify that the mask parameters (for example, Parameter 0:324[Logic Mask]) are configured to receive the desired logic from the option module. See the PowerFlex 750-Series product documentation for details.

755T: Verify that the mask parameters (for example, Parameter 0:41 [Logic Mask]) are configured to receive the desired logic from the option module. See the PowerFlex 750-Series product documentation for details.

The option module is now ready to receive input data and transfer status data to the PROFIBUS leader (controller). Next, configure the controller to recognize and transmit I/O to the option module.

IMPORTANT Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host Parameters 01, 02, and 03 to configure three Datalinks to write data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020 29

Chapter 3 Configuring the Option Module

Enable Datalinks To Read Data

The controller input image (drive-to-controller inputs) can have 0…16 additional 32-bit parameters (Datalinks). They are configured using Host Parameters 17 [DL To Net 01] through 32 [DL To Net 16]. The number of Datalinks actively used is controlled by the connection size in the controller. See the controller example sections in Chapter 4 for more information on setting the connection size.

When using a ControlLogix controller and the Generic Profile, configure the Datalink parameters now as described in this section.

Host Parameters 17 [DL To Net 01] through 32 [DL To Net 16] configure which parameters in the drive, option module, or any other connected peripheral send the values to the network. You can use the PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM, or another drive configuration tool such as Connected Components Workbench, to select the drive or peripheral by port number and the parameter by name. As an alternate method, the parameter value can be set manually by number using this formula:

To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number)

For example, suppose you want to use Host Parameter 17 [DL To Net 01] to read Parameter 2 of an optional I/O module plugged into drive Port 6. Using the formula, the value for Host Parameter 17 [DL To Net 01] would be (10000 * 6)+ (2) = 60002.

Follow these steps to enable Datalinks to read data.

1. Set the values of only the required number of contiguous drive-to-controller Datalinks needed to read data from the drive and that are to be included in the network I/O connection.

2. Reset the option module; see Resetting the Option Module on page 32.

The option module is configured to send output data to the leader (controller). You must now configure the controller to recognize and transmit I/O to the option module.

Setting a Fault Action By default, when communication is disrupted (for example, the network cable is disconnected) or the leader (controller) is idle, the product responds by faulting if it is using I/O from the network. You can configure a different response to these events:

• Disrupted I/O communication by using Host Parameter 33 [Comm Flt Action].

IMPORTANT Always use the Datalink parameters in consecutive numerical order, starting with the first parameter. For example, use Host Parameters 17, 18, 19, 20, and 21 to configure five Datalinks to read data. Otherwise, the network I/O connection will be larger than necessary, which needlessly increases controller response time and memory usage.

30 Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020

Chapter 3 Configuring the Option Module

• An idle controller by using Host Parameter 34 [Idle Flt Action].

Changing the Fault Action

Set the values of Host Parameters 33 [Comm Flt Action] and 34 [Idle Flt Action] to any of these responses.

Figure 6 - Edit Fault Action HIM Screens

Changes to these parameters take effect immediately. A reset is not required.

If communication is disrupted and then is re-established, the drive will automatically receive commands over the network again.

Setting the Fault Configuration Parameters

When setting Host Parameters 33 [Comm Flt Action] and 34 [Idle Flt Action] to ‘Send Flt Cfg’, the values in the following parameters are sent to the drive after a communication fault and/or idle fault occurs. You must set these parameters to values required by your application.

ATTENTION: Risk of injury or equipment damage exists. Host Parameters 33 [Comm Flt Action], and 34 [Idle Flt Action] let you determine the action of the option module and connected drive if communication is disrupted or the leader (controller) is idle. By default, these parameters fault the drive. You may configure these parameters so that the drive continues to run, however, precautions should be taken to verify that the settings of these parameters do not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected network cable or controller in idle state).

Value Action Description

0 Fault The drive is faulted and stopped (default).

1 Stop The drive is stopped, but not faulted.

2 Zero Data The drive is sent 0 for output data. This does not command a stop.

3 Hold Last The drive continues in its present state.

4 Send Flt CfgThe drive is sent the data that you set in the fault configuration parameters (Host Parameters 37 [Flt Cfg Logic], 38 [Flt Cfg Ref], and 39 [Flt Cfg DL 01] through 54 [Flt Cfg DL16]).

Chapter 3 Configuring the Option Module

Changes to these parameters take effect immediately. A reset is not required.

Resetting the Option Module Changes to switch settings and some option module parameters require you to reset the option module before the new settings take effect. You can reset the option module by power cycling the drive or by using Device Parameter 07 [Reset Module].

Figure 7 - Set Device Parameter 07 - [Reset Module] to ‘1’ (Reset Module).

When you enter ‘1’ (Reset Module), the option module will be immediately reset. An alternate method to reset the module is by power cycling the drive. When you enter ‘2’ (Set Defaults), the option module will set ALL of its Device and Host parameters to their factory default values. (This is the same as pressing the ALL soft key when using the MEMORY folder method described in Restoring Option Module Parameters to Factory Defaults on page 33). After performing a Set Defaults, you must enter ‘1’ (Reset Module) or power cycle the drive so that the new values take effect. Thereafter, this parameter will be restored to a value of ‘0’ (Ready).

Option Module Host Parameter Description

Parameter 37 [Flt Cfg Logic] A 32-bit value sent to the drive for Logic Command.

Parameter 38 [Flt Cfg Ref] A 32-bit REAL (floating point) value sent to the drive for Reference.

Parameter 39 [Flt Cfg DL 01] … Parameter 54 [Flt Cfg DL 16]

A 32-bit integer value sent to the drive for a Datalink. If the destination of the Datalink is a REAL (floating point) parameter, you must convert the desired value to the binary representation of the REAL value. (An internet search of ‘hex to float’ provides a link to a tool to do this conversion.)

ATTENTION: Risk of injury or equipment damage exists. If the option module is transmitting control I/O to the drive, the drive may fault when you reset the option module. Determine how your drive will respond before resetting the option module.

IMPORTANT When performing a Set Defaults, the drive may detect a conflict and then not allow this function to occur. If this happens, first resolve the conflict and then repeat Set Defaults action. Common reasons for a conflict include the drive running or a controller in Run mode.

If your application allows, you can also reset the option module by cycling power to the drive (resetting the drive) or by using the HIM’s Reset Device function located in the drive’s DIAGNOSTIC folder.

Chapter 3 Configuring the Option Module

Restoring Option Module Parameters to Factory Defaults

As an alternate reset method, you can restore the option module parameters using a MEMORY folder menu item instead of using Device Parameter 07 [Reset Module] described in Resetting the Option Module on page 32. The MEMORY folder method provides two ways to restore the option module Device and Host parameters:

• ALL—Restores ALL option module Device and Host parameters to their factory default values.

• MOST—Restores MOST option module Device and Host parameters—except Device Parameter 05 [Net Addr Cfg] which is used for network setup.

Follow these steps to restore option module Device and Host parameters to their factory default values.

1. Access the Status screen, which is displayed on HIM power-up.

2. Use the or key to scroll to the Port in which the option module is installed.

3. Press the key to display its last-viewed folder.

4. Use the or key to scroll to the MEMORY folder.

5. Use the or key to select Set Defaults.

6. Press the (Enter) key to display the Set Defaults popup box.

7. Press the (Enter) key again to display the warning popup box to reset Device and Host parameters to their factory default values.

8. Press the MOST soft key to restore MOST Device and Host parameters to factory defaults, or press the ALL soft key to restore ALL parameters. Or press the ESC soft key to cancel.

9. Reset the option module using Device Parameter 07 [Reset Module] or by cycling power to the drive so that the restored parameters take effect.

IMPORTANT When performing a Set Defaults, the drive may detect a conflict and then not allow this function to occur. If this happens, first resolve the conflict and then repeat this Set Defaults procedure. Common reasons for a conflict include the drive running or a controller in Run mode.

Chapter 4

Using the I/O

This chapter provides information and examples that explain how to control, configure, and monitor a PowerFlex 750-Series drive using PROFIBUS DPV0 messaging.

About I/O Messaging PROFIBUS DPV0 or I/O messaging is used to transfer the data which controls the PowerFlex drive and its Reference. I/O messaging can also be used to transfer data to and from Datalinks which are mapped to parameters in the PowerFlex 750-Series products.

The option module includes the Logic Command, Logic Status, Reference, and Feedback (all as 32-bit words) in the controller’s I/O image. This basic I/O must always be configured by the PROFIBUS configuration tool to the 20-750-PBUS option module, enabling the ability to control and monitor the PowerFlex 750-Series product.

Additional I/O if needed, can be configured using up to 16 Datalinks to write data and/or up to 16 Datalinks to read data. When using any combination of these Datalinks, one 32-bit word for each Datalink will be added to the basic I/O Input Size and/or Output Size.

Chapter 3, Configuring the Option Module, and Chapter 4, Configuring the Profibus Master discuss how to configure the option module and controller on the network for the required I/O. This chapter discusses how to use the I/O after you have configured the option module and controller.

Chapter 4 Using the I/O

Understanding the I/O Image The terms ‘input’ and ‘output’ are defined from the controller’s point of view. Therefore, output I/O is data that is produced by the controller and consumed by the option module. Input I/O is status data that is produced by the option module and consumed as input by the controller. The I/O image will vary based on how many of the drive’s 32-bit Datalinks (Host DL From Net 01-16 and Host DL To Net 01-16) are used.

The I/O image can be configured based upon the number of Datalinks required by the user. Table 3 shows the I/O image when using all of the 32-bit Datalinks.

Table 3 - PROFIBUS I/O Image for PowerFlex 750-Series Drives (32-bit Logic Command/Status, Reference/Feedback, and Datalinks)

Using Logic Command/Status

The Logic Command is a 32-bit word of control data produced by the controller and consumed by the option module. The Logic Status is a 32-bit word of status data produced by the option module and consumed by the controller.

• Logic Command word is always the first 32-bit word in the output image.• Logic Status word is always the first 32-bit word in the input image.

This manual contains the bit definitions for compatible products available at the time of publication in Appendix C, Logic Command/Status Words: PowerFlex 750-Series Drives.

Chapter 4 Using the I/O

Using Reference/Feedback The Reference is a 32-bit REAL (floating point) piece of control data produced by the controller and consumed by the option module. The Feedback is a 32-bit REAL (floating point) piece of status data produced by the option module and consumed by the controller.

• Reference word is always the second 32-bit word in the output image.• Feedback word is always the second 32-bit word in the input image.

The Reference and Feedback 32-bit REAL value represents drive speed. The scaling for the speed Reference and Feedback are dependent on drive Parameter 300 - [Speed Units]. For example, if Parameter 300 is set to Hz, a 32- bit REAL Reference value of ‘30.0’ would equal a Reference of 30.0 Hz. If Parameter 300 is set to RPM, a 32- bit REAL Reference value of ‘1020.5’ would equal a Reference of 1020.5 RPM. Note that the commanded maximum speed can never exceed the value of drive Parameter 520 - [Max Fwd Speed]. Table 4 shows example References and their results for a PowerFlex 750-Series drive that has its:

• Parameter 300 [Speed Units] set to Hz.• Parameter 37 [Maximum Freq] set to 130 Hz.• Parameter 520 [Max Fwd Speed] set to 60 Hz.

When Parameter 300 [Speed Units] is set to RPM, the other parameters are also in RPM.

Table 4 - PowerFlex 750-Series Drive Example Speed Reference/Feedback Scaling

Using Datalinks A Datalink is a mechanism used by PowerFlex drives to transfer data to and from the controller. Datalinks allow a drive parameter value to be read from or written to without using a PROFIBUS DPV1 Service. When enabled, each Datalink occupies one 32-bit word in a ControlLogix controller, providing a mirror of the PowerFlex 750-Series drive data value that the Datalinked parameter represents.

The following rules apply when using PowerFlex 750-Series drive Datalinks:• The target of a Datalink can be any Host parameter, including those of a

peripheral. For example, drive parameter 535 - [Accel Time 1] can be the target of any or all option modules installed in the drive.

• The data passed through the Datalink mechanism is determined by the settings of Host Parameters 01...16 [DL From Net 01-16] and Host Parameters 17...32 [DL To Net 01-16].

Chapter 4 Using the I/O

• When an I/O connection that includes Datalinks is active, those Datalinks being used are locked and cannot be changed until that I/O connection becomes idle or inactive.

• When you use a Datalink to change a value, the value is not written to the Nonvolatile storage (NVS) memory. The value is stored in volatile memory and lost when the drive loses power. Thus, use Datalinks when you need to change the value of a parameter frequently.

Datalinks for PowerFlex 750-Series drive peripherals (the embedded EtherNet/IP adapter on only PowerFlex 755 drives and option modules such as an encoder or a communication module) are locked when the peripheral has an I/O connection with a controller. When a controller has an I/O connection to the drive, the drive does not allow a reset to defaults, configuration download, or anything else that could change the makeup of the I/O connection in a running system. The I/O connection with the controller must first be disabled to allow changes to the respective Datalinks.

Depending on the controller being used, the I/O connection can be disabled by doing the following:

• Putting the controller in Program mode• Disconnecting the drive from the network• Placing the leader in idle mode

DeviceLogix Datalinks are also locked while the DeviceLogix program is running. The DeviceLogix program must first be disabled to allow changes to the Datalinks. Set DeviceLogix parameter 53 [DLX Operation] to ‘DisableLogic’ to disable the logic (the parameter value will then change to ‘LogicDisabld’).

IMPORTANT A reset is always required after configuring Datalinks so that the changes take effect.

A COP (Copy) instruction or a UDDT is needed—for REAL parameters, speed Reference, and speed Feedback only—to copy the DINT data into a REAL word for input data conversion. For output data conversion, a COP (Copy) instruction or UDDT is needed—for REAL parameters, speed Reference, and speed Feedback only—to copy the REAL data into a DINT word. To determine whether a parameter is a 32-bit integer (DINT) or a REAL data type, see the Data Type column in the chapter containing parameters in the PowerFlex 750-Series AC Drives Programming Manual, publication 750-PM001, and publication750-PM001, the PowerFlex Drives with TotalFORCE Control Programming Manual, publication 750-PM100.

Acyclic Messaging

This chapter provides information and examples that explain how to use PROFIBUS Class 1 DPV1 Acyclic Messaging to configure and monitor the PowerFlex® 750-Series drive through the 20-750-PBUS option module.

About Acyclic Messaging Acyclic messaging is used to transfer data to the PowerFlex 750-Series drive through the 20-750-PBUS option module and other connected peripherals that do not require continuous updates. Acyclic messaging, or DPV1 messaging in the case of the 20-750-PBUS option module, is also used to configure and monitor a drive's parameters on a PROFIBUS network. Drive parameters as well as peripheral Host and Device parameters can be accessed via acyclic messaging for a PowerFlex 750-Series drive.

For a full list of drive parameters, see the PowerFlex 750-Series AC Drives Programming Manual, publication 750-PM001, and the PowerFlex Drives with TotalFORCE Control Programming Manual, publication 750-PM100. For a list of 20-750-PBUS option module Host and Device Parameters, see Appendix B. To use acyclic messaging read and write services, you need the values of the slot and index to which a parameter is associated. Value ranges for slot and index are shown in Table 5.

Rockwell Automation does not assume responsibility or liability (to include intellectual property liability) for actual use of the examples shown in this publication.ATTENTION: Risk of equipment damage exists. If Acyclic Messages are programmed to write parameter data to Non-Volatile Storage (NVS) frequently, the NVS will quickly exceed its life cycle and cause the drive to malfunction. Do not create a program that frequently uses Acyclic Messages to write parameter data to NVS. Datalinks do not write to NVS and should be used for frequently changed parameters.

Chapter 5 Acyclic Messaging

For accessing any parameter within a drive, a general mechanism is used to map the parameter with a PROFIBUS slot and index number.

Every drive device port has a base slot number which supports 256 indices in a slot. These slot and index combinations are mapped to various drive and option module parameters through the 20-750-PBUS option module. These are the general formulas used to determine the slot and index numbers for a specific parameter.

Slot Number = Base Slot Number + Quotient of (parameter number / 256)Index Number = Remainder of (parameter number / 256)

Chapter 5 Acyclic Messaging

Due to PROFIBUS standard requirements of various identification and maintenance functions, there is an exception to the rule for assigning Host drive parameters. When accessing drive parameters, the slot number will start at 0x01. This is the formula used to determine the slot number for a Host drive parameter.

Slot Number = Base Slot Number + Quotient of (parameter number / 256) + 1

Examples

The following examples illustrate the use of these formulas.

Example 1: 753/755

To access Drive parameter 25 [Motor NP Volts], see Table 5 to find the slot number associated with Port 0, which can be used to access the first 256 parameters. To access parameters 257…512, the slot number will increment by 1, and so on.

For the drive (Port 0), the base slot number is 0x00 + 1 (per the exception). Therefore, the slot number can be calculated using the general formula:

Slot Number = 0x00 + Quotient of (25 / 256) + 1 = 0x01

The index number will be the remainder of the drive parameter number divided by 256, as shown using this formula:

Index Number = Remainder of (25 / 256) = 25

Example 1: 755T

To access Drive parameter 3 [DC Bus Volts], see Table 5 to find the slot number associated with Port 0, which can be used to access the first 256 parameters. To access parameters 257…512, the slot number will increment by 1, and so on.

For the drive (Port 0), the base slot number is 0x00 + 1 (per the exception). Therefore, the slot number can be calculated using the general formula:

Slot Number = 0x00 + Quotient of (3 / 256) + 1 = 0x01

The index number will be the remainder of the drive parameter number divided by 256, as shown using this formula:

Index Number = Remainder of (3 / 256) = 3

Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020 43

Chapter 5 Acyclic Messaging

Example 2: 753/755

To access Host Parameter 37 [Flt Cfg Logic] in the option module when the module is installed in drive Port 4, see Table 5 to find the Slot Number associated with Port 4 Host Parameters.

For Port 4 Host parameters, the base slot number is 0x3F. Therefore, the slot number can be calculated using the general formula:

Slot Number = 0xCF + Quotient of (37 / 256) + 1 = 0xD0

The index number will be the remainder of the Port 4 Host parameter number divided by 256, as shown using this formula:

Index Number = Remainder of (37 / 256) = 37

Example 2: 755T

To access Host Parameter 37 [Flt Cfg Logic] in the option module when the module is installed in drive Port 4, see Table 5 to find the Slot Number associated with Port 4 Host Parameters.

For Port 4 Host parameters, the base slot number is 0x21. Therefore, the slot number can be calculated using the general formula:

Slot Number = 0x21 + Quotient of (37 / 256) + 1 = 0x22

The index number will be the remainder of the Port 4 Host parameter numberdivided by 256, as shown using this formula:

Index Number = Remainder of (37 / 256) = 37

Example 3: 753/755

To access Host Parameter 1 [Sys Rated Amps] in the option module when the module is installed in drive Port 10, see Table 5 to find the Slot Number associated with Port 10 Host Parameters.

For Port 10 Host parameters, the base slot number is 0xE7. Therefore, the slot number can be calculated using the general formula:

Slot Number = 0xE7+ Quotient of (1 / 256) = 0xE8

The index number will be the remainder of the Port 4 Host parameter number divided by 256, as shown using this formula:

Chapter 5 Acyclic Messaging

Example 3: 755T

To access Host Parameter 1 [Output Frequency] in the option module when the module is installed in drive Port 10, see Table 5 to find the Slot Number associated with Port 10 Host Parameters.

For Port 10 Host parameters, the base slot number is 0x3F. Therefore, the slot number can be calculated using the general formula:

Slot Number = 0x3F + Quotient of (1 / 256) = 0x40

The index number will be the remainder of the Port 4 Host parameter number divided by 256, as shown using this formula:

Index Number = Remainder of (1 / 256) = 1

Acyclic Messaging for DPV1 Class 1

The 20-750-PBUS option module provides the following PROFIBUS DPV1 Class 1 Acyclic Services:

• READ—This service is used to read a parameter in the PowerFlex 750-Series drive or the option module.

• WRITE—This service is used to modify a parameter in the PowerFlex 750-Series drive or the option module.

Example Messaging Examples of using PROFIBUS DPV1 Class 1, Acyclic Messaging to read and write a drive parameter is described in this section.

Read Example for Drive Parameter 1 - [Output Frequency]

To read the PowerFlex 750-Series drive parameter 1 - [Output Frequency] using a Class 1 Acyclic Read Service, setup a ControlLogix controller (with a MVI56-PDPMV1 PROFIBUS Module). After the leader is setup, the ControlLogix tags must be populated with the values to read the parameter as shown in Figure 8.

Drive Parameter 1 - [Output Frequency]:

• Slot Number = 0x00 + Quotient of (1 / 256) + 1= 1• Index Number = Remainder of (1 / 256) = 1• Length in bytes of the value of the parameter (32 bit floating point value) /

8 = 4

To test the Read service, you may manually enter the values as shown below into the MVI56-PDPMV1 controller scoped tags, where a ProSoft MVI56-PDPMV1 PROFIBUS leader module is installed in the backplane of the ControlLogix controller rack.

• MVI56PDPMV1.Mailbox.AcyclicRead.Out.SlotNumber = 1• MVI56PDPMV1.Mailbox.AcyclicRead.Out.SlaveAddress = 3• MVI56PDPMV1.Mailbox.AcyclicRead.Out.Length = 4• MVI56PDPMV1.Mailbox.AcyclicRead.Out.Index = 1

Rockwell Automation Publication 750COM-UM004C-EN-P - December 2020 45

Chapter 5 Acyclic Messaging

Next, manually enter a value of '1' into the MVI56PDPMV1.MailboxCommand.AcyclicRead tag, to send the message.

Figure 8 - Acyclic Class 1 Read for Parameter 1 - [Output Frequency]

When the message response successfully returns, the data for the Output Frequency parameter will be placed in the tags MVI56PDPMV1.Mailbox.AcyclicRead.In.Data[] byte array. In the controller program, the return message data may be copied to a locally configured program tag, and converted by correctly assigning the data type for the Local tag to which the data returned from the read request matches. In this drive parameter 1 - [Output Frequency] example, the local tag's data type should be a floating point or a ‘REAL’ data type.

Acyclic Class 1 Read response data can be viewed as shown in Figure 9.

Figure 9 - Acyclic Class 1 Read Response Data for Parameter 1 - [Output Frequency]

Figure 10 shows the RSLogix™ ladder logic example, that may be used to interface the MVI56-PDPMV1 module’s functional block and perform continuous DPV1 Acyclic Read operations.

Write Example for Drive Parameter 520 [Max Fwd Speed]

To write to the PowerFlex 750-Series drive parameter 520 [Max Fwd Speed] using a Class 1 Acyclic Write Service, setup a ControlLogix controller (with a MVI56-PDPMV1 PROFIBUS module). After the leader is setup, the ControlLogix tags must be populated with the correct slot and index addressing values to write the parameter as shown in Figure 11.

Drive Parameter 520 - [Max Fwd Speed]:

• Slot No. = 0x00 + Quotient of (520 / 256) + 1 = 3• Index No. = Remainder of (520 / 256) = 8• Length in bytes of the value of the Parameter (32 bit floating point value)

/ 8 = 4

To test the Write Service, you may manually enter the values as shown below into the MVI56-PDPMV1 controller scoped tags where a ProSoftMVI56-PDPMV1 PROFIBUS leader module has been installed in the backplane of the ControlLogix controller rack.

• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.SlotNumber = 3• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.SlaveAddress = 3• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.Length = 4• MVI56PDPMV1.Mailbox.AcyclicWrite.Out.Index = 8

The data bytes to be written can be entered in the MVI56PDPMV1.Mailbox.AcyclicWrite.Out.Data[] array, or the data may be copied via ladder logic and a locally configured program tag which represents the correct data type, for the data value, to be written to drive parameter 520. In this example, the value would be a floating point or ‘REAL’ data type. The value shown in Figure 11, indicates a value of 60.00 Hz.

Figure 11 - Acyclic Class 1 Write for Parameter 520 - [Max Fwd Speed]

To manually trigger the message to be sent, enter a value of '1' into the MVI56PDPMV1.MailboxCommand.AcyclicWrite tag.

The message response status indicates success when the data in the ‘MVI56PDPMV1.Mailbox.AcyclicWrite.In.ErrorDecode’ tag is a value of 0x00. Note that any non-zero value indicates an error has occurred.

Acyclic Class 1 Write response data can be viewed as shown in Figure 12.

Chapter 6 Troubleshooting

Viewing and Clearing Events The option module has an event queue to record significant events that occur in the operation of the module. When such an event occurs, an entry consisting of the event’s numeric code and a timestamp is put into the event queue. You can view the event queue with any of these drive configuration tools:

• PowerFlex 20-HIM-A6 or 20-HIM-C6S HIM• Connected Components Workbench software, version 1.02 or later

For details on viewing and clearing events with the HIM, see the PowerFlex 20-HIM-A6/-C6S HIM (Human Interface Module) User Manual, publication 20HIM-UM001.

The event queue can contain up to 32 entries, which are stored in an EEPROM chip—making the event queue nonvolatile. Eventually the event queue will become full, since its contents are retained through option module power cycles and resets. At that point, a new entry replaces the oldest entry. Only an event queue clear operation or the corruption of the EEPROM group containing the event queue will clear the event queue contents. In the latter case, the option module will not generate a fault to indicate that the event queue was corrupted.

Appendix B Option Module Parameters

33 [Comm Flt Action]Sets the action that the option module and drive will take if the option module detects that I/O communication has been disrupted. This setting is effective only if I/O that controls the drive is transmitted through the option module. When communication is re-established, the drive will automatically receive commands over the network again.

Default: 0 = FaultValues: 0 = Fault

1 = Stop2 = Zero Data3 = Hold Last4 = Send Flt Cfg

Type: Read/WriteReset Required: No

34 [Idle Flt Action]Sets the action that the option module and drive will take if the option module detects that the controller is in program mode or faulted. This setting is effective only if I/O that controls the drive is transmitted through the option module. When the controller is put back in Run mode, the drive will automatically receive commands over the network again.

Default: 0 = FaultValues: 0 = Fault

1 = Stop2 = Zero Data3 = Hold Last4 = Send Flt Cfg

Type: Read/WriteReset Required: No

35 [Peer Flt Action]This parameter is functional. However, since the option module does not support peer I/O, any entered value is not used.

Reserved

36 [Msg Flt Action]The option module does not support this functionality. Any entered value is not used.

ATTENTION: Risk of injury or equipment damage exists. Host Parameter 33 - [Comm Flt Action] lets you determine the action of the option module and connected drive if I/O communication is disrupted. By default, this parameter faults the drive. You may configure this parameter so that the drive continues to run, however, precautions should be taken to verify that the setting of this parameter does not create a risk of injury or equipment damage. When commissioning the drive, verify that your system responds correctly to various situations (for example, a disconnected cable).
